Before performing the following procedures, read “Safety Notices” on page xi.
Removing a Processor Fan in a Non-Hot-Swap Environment
Note: A processor fan in a non-hot-swap environment means that your system is configured at the factory
with one processor fan installed. To place your system into an environment that enables the
hot-swapping of the processor fans, you must purchase a second processor fan and insert it into
the unused docking connector. It is not necessary to shut down the system when adding the
second processor fan.
To remove a processor fan in a non-hot-swap environment, do the following:
1. On a Model 6C4, open the front and rear rack doors and place the system into the service position as
described in “Placing the Model 6C4 into the Service Position” on page 429.
On a Model 6E4, open the bezel door.
2. Shut down the system as described in either “Stopping the System without an HMC Attached” on
page 424, “Stopping the System with an HMC Attached and AIX Installed” on page 424, or “Stopping
the System with an HMC Attached and Linux Installed” on page 425.
3. Disconnect the power source from the system.
Note: This system may be equipped with a second power supply. Before continuing with this
procedure, ensure that the power source to the system has been completely disconnected.
4. Continue with the procedure in “Hot-Swap Fan Assembly Removal” on page 462.
